'96 Polaris SLX Impeller Needed

A friend just gave me this 780 SLX ski that was sitting for a couple of years. It appeared to be frozen but after removing the impeller it seems this impeller and extension were frozen together. After removing the impeller, the motor turned over nicely. Removed and cleaned out fuel tank replaced with new gas and seems to idle nice...except when I give it some throttle it seems to bog down.

Soooo, I need to start somewhere. I guess the impeller will be first and then the carbuerator? Can anyone give me some input?

As for the bog, replace the aging fuel system and rebuild the carbs, Contact Jay at sharp's Marine or John zigler at Rock County Jet ski for genuine Mikuni carb rebuild kits. ONLY buy genuine parts when rebuilding carbs.
